Or neither?
I have 3 sets of wheels if you count the single S60. I have the original 105 hubs/CXP-22 wheels, a set of Williams System 30, and the single S60. The CXP-22 wheels will be going on the bike soon and stay until spring. The rear System 30 is on the bike all summer. The front swaps between the S60 and System 30. I only use the S60 on reasonably calm days or when I am riding by myself, which is less and less these days. The reason being is that the group I normally ride with rides fast and very close together. I don't want to take any chances if it is a little windy. I don't have a power meter, so this is only feel, but the S60 is easier to push through the air than the System 30 by a noticable amount. The biggest change is the feeling when the front wheel rolls off and leaves me to pull. With the System 30 there is much more of a "wall" when that happens then with the S60.
But it might just be in my head, since I am an engineer and my education tells me that the deep rim should slice the air better. If I were to check on a power meter it might not mean anything.
But you have to admit, there is a really big "bling" factor with an S60 wheel
